Pre-AP Biology: Ecology Vocab Part 2: ECO 3, 4, 5

Front

A species on which other species in an ecosystem largely depend, removal of which drastically changes the ecosystem.

Back

Keystone species

Front

Amount of different organisms in an area maintained by a stable food web and environment.

Back

Biodiversity

Front

Biome with dry, hot summers and cold winters

Back

Temperate grassland

Front

Area of Earth defined by precipitation and temperature

Back

Biome

Front

Natural progression over decades, slowed by disasters. Faster if soil is intact with nutrients.

Back

Ecological succession

Front

Largest terrestrial biome with shortest growing season.

Back

Taiga

Front

Competing species use the environment differently to coexist.

Back

niche partitioning

Front

Gradual establishment of biotic communities in lifeless areas (e.g., newly formed island).

Back

Primary ecological succession

Front

One organism benefits, the other neither benefits nor is harmed.

Back

Commensalism

Front

Species that invade new ecosystems and harm native species.

Back

Invasive species
